Filter by:This will be a single center, methodological study in healthy male subjects to evaluate the intra-period, inter-period and inter-observer reproducibility of flow measurements in the superior mesenteric artery, using Doppler Ultrasound.
The objective is to validate the use of ultrasound measurements (urethral mobility, movement of the ano-rectal angle, elastography measurements) in women with urinary incontiennce before and after pelvic floor muscle training (PFMT) : inter and intra-observer reproducibility; correlation with clinical examination (modified Oxford scale); sensitivity to change before/after pelvic floor muscle training
The purpose of this study is to test whether ultrasound images (pictures) can be used as a valid assessment of muscle quality in different muscle groups during Intensive Care stay. This new approach would allow clinicians to obtain frequent skeletal muscle images and would enable doctors to observe any changes over time in muscle quality that could occur during ICU stay. Participants in this study will have ultrasound images made of their leg-, chest- and jaw muscles taken on every day until ICU discharge.
Endovaginal ultrasound is currently the gold standard to diagnose a shorted cervical length and, by extension, assess the risk of preterm labor. The major inconvenient is that this is an invasive method of diagnosis that tends to be poorly accepted by some patients. This study aims to evaluate the accuracy of a noninvasive transperineal ultrasound cervical measurement in comparison to the endovaginal technic in 2nd and 3nd trimester pregnant women where a cervical ultrasound is indicated.
The current COVID-19 pandemic is providing healthcare organizations with considerable challenges and opportunities for rapid cycle improvement efforts, in diagnostic and patient management arenas. Healthcare providers are tasked with limiting the use of personal protective equipment while minimizing unnecessary exposures to the virus. Results from real-time PCR tests to detect active COVID-19 infections may not be available in a timely fashion during emergent trauma assessments. Since the start of the COVID-19 pandemic, a rapidly expanding body of literature has identified a pattern of imaged lung abnormalities with CT and ultrasound (US) characteristic of an active viral infection. US evaluation provides a reliable, portable, and reproducible way of evaluating acute patients in a real time setting. During initial trauma evaluations, patients may also receive adjunct imaging modalities like the Focused Assessment with Sonography in Trauma (FAST) exam designed to discover life threatening findings that may require urgent interventions. We therefore propose a study expanding on the current FAST adjunct evaluation in the trauma bay that may include lung parenchyma imaging at the initial assessment to help stratify patients into low or high-risk groups for active COVID-19 infections. We believe the use of point of care US in the initial assessment of the trauma patient may help identify potentially infected individuals and aid ED providers to best directing subsequent laboratory and imaging evaluations for these patients, while further directing the necessary protective measures for additional team members involved in the care of the injured patient.
We aimed to investigate the effect of kinesiotaping on pain, functionality and ultrasound parameters in patients with shoulder impingement syndrome (SIS).
Recurrent fluid surrounding the lungs is associated with poor quality of life, the main symptom being dyspnea. These patients are in need of recurrent removal of the fluid using drainage. The mechanism causing dyspnea is not fully understood. By using ultrasound to evaluate the movement of the diaphragm before and after removal of fluid and the patients symptoms before removal of fluid and until next removal the research group aims to clarify the temporal development in symptoms and the role of the diaphragm. The researchers will also evaluate the ability of the pulmonologist and patient to predict when the patient will need the next removal of fluid in patients with recurrent unilateral pleural effusion.
The value of lung ultrasound in the work up of pleural effusion (fluid in between the thin doublet layered film surrounding the lungs) is unknown. The researchers will perform a systematic lung ultrasound scan including a scan for extra thoracic metastasis (spread of cancer to other organs) in the lymphnodes of the neck and metastasis lever in 56 patients one-sided pleural effusion. The researchers will measure if the interventions change the diagnostic plan for the patient and leads to faster diagnostics of the underlying course.
The study aims to provide a timely update on the role of combining clinical and neuromuscular ultrasound assessments in diagnosis and follow-up of various muscle diseases in clinical practice over 12 months period, and correlating US findings with functional scales, biochemical and electrophysiological studies.
